[Efficacy and safety of autohemotherapy at acupoint for acne: systematic review].

OBJECTIVE

To evaluate the efficacy and safety of autohemotherapy at acupoint for acne.

METHODS

Randomized controlled trials (RCTs) regarding autohemotherapy at acupoint for acne were searched in CNKI, WanFang, VIP database and PubMed. According to the inclusion and exclusion criteria, two investigators performed the literature screening, data extraction and basis evaluation, independently. Meta analysis was performed by using Review Manager 5.3 software.

RESULTS

Eight RCTs were included, involving 573 patients. The combined effect of effective rate was 1.21 (95% Cl : 1.12, 1.30); the combined effect of skin lesions improvement was -1.00 (95%Cl: -2.14, -0.14, Z＝1.73, P=0.08); the combined effect of recurrence rate was 0.44 (95%Cl: 0.09, 2.15, Z＝1.01, P=0.31).

CONCLUSION

The autohemotherapy at acupoint has better efficacy and skin lesions improvement for acne than control treatment, and autohemotherapy is safer.
